HEEL-NAILING MACHINE FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 310,488, dated January 6, 1885.

Application filed May 3, 1884. (No model.)

To whom it may concern.-

Be it known that I, EDWARD B. ALLEN, residing in Portland, in the county of Cumberland, State of Maine, have invented certain new and useful Improvements in Heel-N ailing Machines for Boots and Shoes, whereof the following description, with the accompanying drawings, is a specification, like letters indicating like parts.

The invention herein to be described is intended as an improvement upon the machine represented in United States Patent No. 203,440, granted to O. V. Glidden, or upon what is known in the market as the McKay & Bigelow Heeling-Machine. In that ma chine the top lift to complete the nailed heel is presented to or laid upon the upper side of the usual pivoted top-lift plate by hand, and so, also, the top-lift plate, located next the top of and resting directly on the nail-boX to support the top lift, and which, when the top lift is being applied, is turned into position to cover the nail-holes in the said nail-block, is moved by hand. Operating the top-lift plate by hand and then placing said top lift there on by hand prevents the rapid operation of the said machine, and it is necessary to run it at a very much slower speed than that at which itmight be practically run.

One special feature of my invention is to provide mechanism whereby the top-lift plate may automatically be turned quickly into position after the body of each heel has been nailed upon the boot or shoe.

Another feature of my invention is to provide a mechanism whereby the top lift may be automatically presented in correct or central position upon the top-lift plate, in order that the top lift may be correctly attached to the protruding ends of the nails of the heel. I have also provided a hook or latch to prevent rebound of the die-bed spindle.

Figure 1 is apartial left-hand side view of a heel-nailing machine of usual construction, with my improvements attached. Fig. 1 is a sectional detail taken in the line 00 00, Fig. 1, looking down. Fig. 2, on a smaller scale, rep resents by dotted lines the upper portion of the right-hand side of a heel-nailing machine, 50 my improved top-platemoving mechanism being added thereto in full lines; Fig. 3, an enlarged detail of the latch which holds the actuating slide-rod of the top-lift carrier; Fig. 4, an enlarged detail of the device which trips the latch; Fig. 5, details of the rod-carrying latch. Fig. 6 shows the latch mounted on the slide-rod of the top-lift carrier, and the spring for moving thesaid rod-carrying latch. Fig. 7 is a top or plan view of the top-lift carrier, shown as holding a top lift between its jaws; Figs. 8, 9, and 10, details of some of the devices shown in Fig. 7. Fig. 11 is a detail of the actuating slide-rod referred to in connection with the spring which carries it forward; Fig. 12, a section of Fig. 11 in the line :0 :0,- Figs. 13 to 15, inclusive, enlarged details of the devices located between the usual toggle mechanism of the said patented machine and the rod which actuates the top lift plate. Figs. 16 and 17 show details of mechanism to prevent the rebound of the die-bed spindle; Fig. 18, a detail in side View of the devices for moving the top-lift plate automatically; Fig. 19, a detail of the actuating slide-rod for the top-lift carrier.

The framework A A, sprocket or chain wheels M N, chain 0, chain-moving carriage K, lever K to move it, the track 0 on which the carriage is moved, the toggle-j oint connec tion T T, lever T", nail-box E, and die-bed spindle WV, are all substantially as in the said patent, so need not be here further specifically described.

Toautomatically present the top lift, L, between the top-lift plate It, pivoted at R at the top of the usual naiLbox, E, and the end of the heel attached to the shoe carried by the usual jack, (the said heel having the heads of the nails protruding therefrom, as usual, to have the top lift impaled on them at the next ascent ofthe die-bed spindle W,) I have provided a top-lift carrier composed, as herein shown, of pivoted or yielding jaws 0 0, carried by levers or arms 12 a, mounted on a head having connected with it means to move the said carrier horizontally. The jaws are pivoted upon the levers or arms a at and the said levers are pivoted at m on the head j, springs g acting to keep the jaws pressed toward thetop lift. The jaw m" on the rod 0 acts 100 against the curved end of the top lift. The head j is connected with a slide-block, f, by means of a dovetail projection, t, on one entering a correspondingly-shaped groove on the other, screws is holding the same in adjusted position. The block f is adj ustably attached to a projecting arm, (I, of the slide-rod a, placed in suitable bearings, b b and 0, fixed with relation to the frame-work A A, the bearings I) being shown as forming part of a plate, I), attached to the frame A.

To prevent rotation of the slide-rod a, in its bearings, the said rod is shown as made square from its shoulder 13 forward, and the bearing 0 has an opening of corresponding shape in cross-section; but,instead,the slide-bar may be round and be provided with a groove to cooperate with a spline, the said spline and groove preventing the rotation of the said rod. The slide-rod has attached to it by suitable screws the collars d, 2 'v, and a. Between the collars c and a the slide-rod is surrounded loosely by the rod-carrying latch Q, (see Figs. 1 and 5,) having at its lower end a toe, t, the upper end of the said latch being acted upon by one end of a spring, y, coiled about the rod (1, and connected at its other end with the bearing 1), the said spring acting to keep the lower part of the said latch against a latchoperating device composed of a bar, I, mounted on brackets H, the inner edge of the said bar being inclined, as shown in Fig. 1, with relation to the frame-work A A, and consequently with relation to the slide-rod a,which is parallel with relation to the frame-work. The slide-rod a is surrounded loosely by a collar, c, joined to the bearing 1) by links a, and between the collar d,fast to the said slide-rod, and the stationary yet loose collar 0, referred to, the slide-rod is surrounded by a spiral spring, 0'', the normal tendency of which is to move the slide-rod a and its attached toplift carrier from its full-line position, Fig. 1, into its dotted-line position, the carrier at such movement takingatop lift, L, from above the shelf S, attached to the framework A. The slide-rod a has a notch, D, which, when the said slide-rod is in its farthest position to the left, (see Fig. 1,) as in full lines, is engaged by the rot'treleasing lever or catch f, pivoted at a on a lug, g, near the bearing 1), the said lever f being kept pressed toward the rod by a spring, h.- Vhen the rod is so held back,the spring 0 is compressed between the collar 0 (the position of which is fixed) and the collar (1; and if the lever or catch f is moved to release it from the said rod, the spring 6 will immediately throw the rod a forward into its dotted-line position, thus enabling the carrier to placea top lift in position to be secured to the heel.

To turn the rod-releasing lover or catchf at the proper time and release the rod a, I have connected with. the lower member, T, of the usual toggle-lever, that turns the beam or lever T, a tripping device composed of a bar, i, pivoted at 7;,and sliding in a guide, Z, the said bar having a dog, j, pivoted upon it at F, the said dog having a hole which is entered by a spring, 7", (see Fig. 4,) the said spring normally keeping the said dog in the position shown in Fig. 4, with its acting end extended beyond the bar i, so as to strike the lever or catchf as the said bar is moved in the direction of the arrow thereon, Figs. 1 and 4, and turn the said lever or catch to release the rod 0. The lever or catch having been moved to release the rod a and throw the collars d c a and the rod-carrying latch and the top-lift carrier into their dotted-linepositions, the said carrier must be withdrawn away from the top-lift plate and nail-boX to permit the usual heeltrimmer to operate. The heel trimming mechanism, of usual construction, derives its movement from the chain 0 over the sprocketwhcels or chain-pulleys M N, and the chain is moved by the vibrating lever K,connected by aslot and pin with the carriage K, grooved to slide or ride on the track 0 As this chain is started in the direction ofthe arrow thereon to trim the heel, as usual, the toe t of the rod-carrying latch Q, acted upon at its upper end by the spring 7 is caught by the carriage and carried along in unison with the same, and

the said latch, held on the rod a between the two collars c and it, acts to move the rod backward and the carrier away from the top-lift plate; but as soon as the said latch has been moved back far enough to compress the spring (2 and carry the notch D in the rod a opposite the lever or catch f, then the latter will im mediately snap into the said notch and hold the rod until it is again released. As the can riage moves the latch Q backward or toward the rear of the machine, as described, the latch is made to travel at first near the inclined edge of the bar 1, and is finally brought against the said edge, and by the time the lever or catch f has engaged the notch the latch Q is moved so far about the rod a as a center by the bar I as to remove the toe 25 from engagement with the carriage K. As the bar 2" is moved back ward the dog j, as it strikes the latch f, turns on its pivot t, the spring XV yielding, and the latch f is not moved out away from the rod a. The pin t acts as a stop for the dog as the bar i is moved forward or in the direction of the arrow. The rod a having been caught by the lever or catch f, the chain is thereafter reversed to return the usual trimming mechanism into its normal position. The acting faces of the jaws 0 and m are serrated. The springs q and 0' act to keep the jaws pressed in the proper direction to hold the top lift. The devices shown in dotted lines, Fig. 2, to hold the shoe, are or may be all as usual in United States Patent No. 203,440, or as in the said McKay & Bigelow heeling-machine, and the said devices will operate all as usual;

Referring to Figs. 2 and 18, I will now describe one practical manner of operating the top-lift plate automatically. The top-lift plate R, pivoted, as usual, on the top of the nail-box E at B has a laterally-extended arm,

R provided with a pin or projection, 12, which is engaged by a rod, .2, held in a yielding manner in the end of the part :0 of a connecting-rod, q :13 e, for automatically actuating the top-lift plate R. The part q of the said connecting-rod has a collar, 1', provided with a pin, which is Connected by link 1) with a lever, 19 pivoted at p, the said lever being in turn connected by a link, 19, with the pin 0*, which forms the junction of the two parts of the toggle T, and as the toggle is operated in usual manner the rod is moved backward and forward in the bearings 0r guides 'V and At its forward end the part q of the connecting-rod has a vertical hole that receives a pin, 13, at the rear end of the part x of the said rod, the said pin and hole permitting the part :0 to rise and fall independently of the part without destroying their connection. The end ofthe part as is provided with a disk-like end, 14, (see Fig. 18,) open at its center, and for a distance back from the said end the said part as is slotted to receive one end of the part 2, the latter having fastened to it two collars, 15 16, and being provided with two cushion-springs,17 18, one at each side the disk 14,whereby the part z is free to yield to a certain extent as the connecting-rod is reciprocated. Movement of the connectingrod described forward toward the operator causes the top-lift plate It to be turned aside ottthe nail-block E, in order that the diebed spindle V, as it is next lifted, will, through usual devices actuated by it, drive nails into the heel to attach it to the sole, leaving the heads of the nails protruding, to have the top lift, L, impaled thereon, as usual; and the nails having been driven into the heel, the backward movement of the top-lift-plate moving or connecting rod, q, described effects the turning of the top-lift plate into position above, and to cover the nail holes in the nailbox E preparatory to placing the top lift in position above it for the second rise of the die-bed spindle W', as usual, to attach the top lift and trim the edge of the heel. The toplift plate and the top-lift carrier are automatically operated in the same time as relates the one to the other, and with such relation to the movements of the toggle and die-bed spindle and trimming mechanism as to cause the toplift plate to cover the nail-box before the top lift is brought into position above the nail-box, the top-lift carrier placing a top lift between the top-lift plate and the lower end of the attached heel as or just before the die-bed spindleis moved to effect the securing ofthc top lifttotheheel. AsthetoggleisbentitsjointO is moved toward the front of the machine, the rod q is operated to turn the top liftplate into position to cover the nail-box, and simultaneous therewith the toplift carrier is'operated to place a top lift between the said plate and the heel attached to the shoe. The diebed spindle IV has attached to it at one side, between its two bearings j and j, a block, h which has pivoted upon it at 48 a hook, g,

acted upon by a spring, Z, and adapted at each descent of the said spindle to engage the bearing 3'' and prevent the die-bed spindle from jumping. To release this hook I have provided a lever, Z", pivoted at and acted upon by a footlcver or treadle, J through alink, m

In another application filed by me May 3, 1884, Serial No. 1352M, I have shown a toplift plate operated in one direction by hand and in the other direction by a spring.

I am aware that a so-called spanker or holder has been supplied with a top lift, and that the said holder in its rotation has placed the top lift above the tread of the heel, the plate of the said spanker or holder serving to resist the thrust of the ends of the nails left protruding beyond the tread of the heel.

Prior to my invention I am not aware that a top-lift plate has ever been automatically swung onits pivot above the nail-box, either to cover or to uncover the nail-box.

I claim 1. In a heelingmachine, the combination, with the nail-box and a top-lift plate,of means, substantially as described, to automatically move the said plate into position above the nail box to cover the same preparatory to applying the top lift, substantially as described.

2. In a heelingmachine, the top-lift plate and the nail-boX, combined with a connectingrod to automatically operate the said top-lift plate to move it into or out of position with relation to the nail-box, substantially as described.

3. In a heelingmachine, the nail-box, c0n1- bincd with a top-lift carrier, substantially as described, to engage a top lift and place it in position between the top-lift plate and the end of the heel, to operate substantially as de scribed.

5. The nail-box and the top-lift carrier, having jaws to grasp and hold the top lift, combined with the slide-bar and means to reciproe-ate it and the carrier forward and backward with relation to the nail-box, as and for the purpose described.

6. A plate or table, S, and the top-lift carrier and nail-box, combined with means to move the said carrier to present a top lift in position below the heel of the boot or shoe with which the top lift is to be attached, and to thereafter withdraw the said carrier, substantially as described.

7. In a heel-nailing machine, the nail-box, the top-lift plate, and means to automatically operate the said top lift plate, combined with the top'lift carrier and with means to automatically operate it, substantially as described.
